2 Claims.

This invention relates to a dumping body, and has relation more particularly to a device of this kind comprised in trucks, wagons and other carriers used in the transportation of large quantities of coal, wood, sawdust, grain and other fluent commodities.

It is a particular object of the invention to provide a body of this kind with means to expedite the discharge of the load in a manner eliminating excessive cost of manual labor.

The invention also has for an object to provide a body of this kind having an unloading mechanism associated therewith, such mechanism being of a character to permit of access to the body for unloading in places where low overhanging structures or other obstructions prevent the use of elevating dump trucks now in use.

Another object of the invention is to provide a body for a carrier on which is mounted a pusher element riding along the floor or bed of the body from the head of the body to the tail to force out at the tall the load carried by the body.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved dumpingbody whereby certain important advantages are attained; as will be hereinafter more fully set forth.

In order that my invention may be the betterunderstood, I will now proceed to describe the same with reference to the accompanying drawings, wherein:

Figure 1 is a vertical sectional view taken through a body constructed in accordance with an embodiment of my invention;

Figure 2 is an enlarged transverse sectional view taken substantially on the line 2-2? of Figure 1;

Figure 3 is an enlarged detailed sectional view taken substantially on the line 3-3 of Figure 2;

Figure 4 is a fragmentary view in perspective of the pusher element unapplied; and

Figure 5 is a diagrammatic view in perspective illustrating the means for operating the pusher element as herein embodied.

As disclosed in the accompanying drawings, E denotes a wagon body including a floor or bottom i, side walls 2, and a removable tail gate 3. The head 4 of the body B may be constructed as desired. It is to. be stated that the body B is adapted to be mounted upon any desired chassis, and the body Bis of a type to be used in the transportation in large quantities of coal, wood,

gravel, dirt, sawdust, grain and other fluent commodities.

The bottom or floor I has mounted at substantially its transverse center the longitudinally disposed and parallel sills 5. These sills ii are equi-distantly spaced as desired at opposite sides of the transverse center of the iioor or bottom I and extend from the head 5 oi the body B to the tail or discharge end. Resting from above on these sills 5 and substantially coextensive in length therewith is a plate having depending from its central portion the longitudinally disposed flanges which extend between the sills 5 and have close contact with the opposed faces of the sills. This plate 6 at a point substantially midway of the sills 5 is provided therealong with a slot 8 which is normally closed by the inwardly disposed flaps 9, preferably of a rubber compound, which are carried by and suitably secured to the under faces of the plate 5. These flaps 9 normally close the slot ii, yet readily allow for movement along the slot 8, the pins iii extending upwardly from the opposite end portions of a hollow or tubular boxing or runner it open at its opposite ends. Each of the pins it intersects the interior of this boxing or runner ii and is fixedly secured to the upper and lower walls thereof. The upper end portion of each of the pins I0 is also disposed upwardly through a sliding plate or carriage ll of desired length and of a width to extend outwardly beyond the sills 5. The extended side portions of this plate 52 have suitably secured thereto the runners it which are closely adjacent to the sills E5 and in parallelism therewith. These runners it have direct contact upon the metallic tracks it secured to the upper face of the floor or bottom 5 of the body B, and extending substantially from one end to the other. The runners it support the plate or carriage i2 slightly above and free of contact with the plate 6 and the upper end portion of each of the pins id is provided with a head or enlargement it which contacts with the upper face of the plate or carriage i2, whereby the boxing or runner ii is suspended from the plate or carriage iii tree of contact with the bottom or floor l oi the body B.

The runners it are comprised in the base structure or a pusher element E and are interposed between and suitably secured to the front and back cross members ii. The extremities of the members i? are connected by the outer shoes i8 which contact from above and ride on the hat tracks is secured to the upper iace oi the floor or bottom i of the body B immediately adjacent to the side walls 2 thereof. The rear cross member IT, at desired spaced points therealong, has rigidly secured thereto the upstanding posts 20, the upper portions of which having secured thereto a rearwardly facing top plate 2|. The lower margin of this top plate 2| is continued by a downwardly and rearwardly inclined bottom plate 22 which is supported upon the upwardly and rearwardly inclined brace members 23 interposed between the forward cross member l1 and the posts at points slightly below the center of said posts. This wall or plate 22 has its lower margin defined by a depending apron-24 which overlies the outer."

face of the adjacent cross member H. The plates 2| and 22, together with the apron 24, are preferably comprised in a single sheet of metal, although I do not wish to be understood as limiting myself in this respect. The floor or bottom i of the body B, at opposite ends thereof and between the sills 5, is provided with the openings 25 through which extend from below the upper portions of the guide pulleys 26. Each of these pulleys 26 is rotatably supported by a suitable bearing 21 secured from below to the bottom or floor I.

Rotatably supported by and below the floor or bottom I of the body B, at a point substantially midway the ends thereof, is a transversely disposed drum or Windlass 28 upon which wind and unwind the flexible members or cables 29 and 30. The cable 29 extends from the drum or Windlass 28 to the rear pulley 26 and up over said pulley, and over the top of the floor or bottom l of the body B, and secured to a pin 3| carried by and intersecting the rear end portion of the slide or boxing II. The second cable or flexible member 30 extends forwardly of the body B and up over the pulley 26 and secured to a pin 32 carried by and intersecting the opposite end portion of theboxing or slide II. It is believed to be obvious that upon requisite rotation of the drum or Windlass 28 the pusher element E will be moved toward the tail end of the body B to discharge the load as desired and, of course, upon opposite rotation of the drum or windlass 28, the element E will be returned to its position at the head end of the body B before reloading.

The drum or Windlass 28 may, of course, be rotated in any manner preferred, but in the present embodiment of my invention one end of the drum or Windlass 28 is provided with a gear 33 concentric to the axis of the drum or Windlass 28, and meshing with this gear 33 is a pinion 34 carried by a shaft 35. This shaft 35 extends forwardly of the body a desired distance and is operatively engaged with a conventional transmission T including an operating lever 36, and upon proper manipulation of this lever 36 the drum or Windlass 28 may be caused to rotate in the direction desired. As the particular construction and operation of this transmission T forms no part of the present invention, a detailed description and illustration is believed to be unnecessary, although it is to be stated that this transmission T, or more particularly the lever 36, is preferably positioned at a point readily accessible to the driver of the vehicle carrying the body B, so that it will not be necessary for him to leave his seat when it is desired to empty the body B of its load as a result of the rearward travel of the element E.

From the foregoing description it is thought to be obvious that a dumping body constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated.

I claim:

1. A carrier body having a head end and a. discharge end and a floor, spaced sills mounted upon the floor and extending substantially from one end of the body to the other, said sills being at substantially the transverse center of the floor, a plate mounted on the sills and bridging the space therebetween, said plate being of a length substantially coextensive to the length of the sills, said plate having a slot extending from substantially one end to the other, a pusher element within the body and mounted upon the floor of the body for movement from one end to the other, a runner positioned between the sills, upstanding pins carried by the runner and extending through the slot of the plate and operatively engaged with the pusher element, said pins holding the runner in suspension from the pusher element, and means operatively engaged with the runner for moving the pusher element in either direction along the floor of the body, said pusher element including shoes riding on the floor of the body.

2. A carrier body having a head end and a. discharge end and a floor, spaced sills mounted upon the floor and extending substantially from one end of the body to the other, said sills being at substantially the transverse center of the floor, a plate mounted on the sills and bridging the space therebetween, said plate being of a length substantially coextensive to the length of the sills, said plate having a slot extending from substantiallyone end to the other, a pusher element within the body and mounted upon the floor of the body for movement from one end to the other, a runner positioned between the sills, upstanding pins carrier by the runner and extending through the slot of the plate and operatively engaged with the pusher element, said pins holding the runner in suspension from the pusher element, a windless operatively supported by the body therebelow, flexible members secured to the opposite end portions of the runner, and guide pulleys carried by the body adjacent to the opposite ends thereof, said flexible members passing over said guide pulleys and winding upon the Windlass so that rotation of the Windlass will move the pusher element along the body.
